Abstract
Coherent forward scattering spectroscopy having the Voigt configuration was applied in the determination of copper in steels, zinc and tin. Copper (0.0005–0.2%) in these metals could be determined without preconcentration procedure. The relative standard deviations were 4.4% for 0.0035% copper and 7.1% for 0.067% copper in steel. The reproducibility of calibration curves for copper in steels (log-log plotting with a slope of about two) was about 18% and the limit of detection was about 0.4 ± 0.07 ng/10 μl.
